Why Is DRS Being Replaced by MOM in F1? New regulation
- By Dr. AK Rana
Let’s talk about how Formula 1 is reinventing overtaking from 2026! DRS is going out, and MOM is coming in.
But what’s the real difference?
Let’s break it down:
…
What is DRS (Drag Reduction System)?
DRS was introduced in 2011.
It opens a flap on the rear wing to reduce drag.
Only used in special DRS zones if you’re within 1 second of the car ahead.
Helps you go 10–12 km/h faster on straights.
…
Physics:
Less drag = more speed.
But also = less downforce, so the car can feel unstable
…
Implication:
DRS made overtaking easier, but many fans felt it made things too predictable.
…
What is MOM (Manual Override Mode)?
From 2026, DRS is gone.
MOM replaces it.
MOM is Formula 1’s fresh approach to overtaking for 2026. Instead of relying on a movable rear wing, drivers will now have a manual override to unlock additional electrical power for overtaking.
This taps into the hybrid engine’s electric side, providing a short power boost that the driver can control.
How it works:
…
MOM gives the pursuing driver access to more battery power for a limited time.
The defending driver cannot use the same boost while being attacked.
…
Physics:
Electric motors = instant torque = faster acceleration.
No change in aerodynamic profile, so cars stay stable through fast corners.
…
What is Active Aerodynamics?
Along with MOM, 2026 F1 cars will feature active aerodynamics. These allow the wings to adjust based on driving conditions:
…
“Z-mode” for high downforce in corners.
“X-mode” for low drag on straights.
Unlike DRS, these wing changes are not for overtaking, but for efficiency and handling.
They will be driver-activated but in a more controlled, symmetrical way.
…
DRS vs MOM – Quick Comparison
Tech Used:
DRS = rear wing flap
MOM = electric power boost
Activation:
DRS = limited zones
MOM = flexible, driver-controlled
Effect:
DRS = lower drag
MOM = more power, instant torque
Stability:
DRS = less stable in corners
MOM = stable, no aero change
Style:
DRS = often predictable
MOM = more strategic
…
What Does This Mean for Racing?
✅ More driver skill: With MOM, drivers will need to plan their overtakes, manage energy deployment, and choose the right moment.
✅ Cleaner battles: Active aero and MOM won’t alter car balance mid-corner like DRS sometimes did. Expect tighter, wheel-to-wheel action.
⚠️ Potential downside? Battery power is limited. If overused early, drivers might run out of boost late in the race.
—
F1’s switch from DRS to MOM isn’t just technical – it’s about giving more power back to the drivers.
It’s cleaner, smarter, and definitely more exciting!
2026 will be a whole new game 🏁
